Abstract:
Objective To design a hyperbaric oxygen chamber ambulance to meet the requirements for on-site hyperbaric oxygen treatment and transport of casualties.Methods A hyperbaric oxygen chamber ambulance was formed based on a YJ2080 wheeled armored vehicle,which had the components of a chamber,a gas source,an oxygen source,a control system and a power source.The chamber had a 3-layer composite structure,with a high-strength metal frame in the outer layer,a capsule made of polyurethane material bound with nylon pressure-resistant tape in the inner layer and a layer of thermal insulation material filled between the chamber and the vehicle;the gas source was composed of the oil-free air compressor,gas cylinder and pressure reducer;the oxygen source was made up of the 20 L oxygen generator,oxygen booster pump and 40 L oxygen cylinder;the control system involved in an EX2N-100HA series touch screen programmable logic controller(PLC)all-in-one(AIO);an ACD-15.0DR/48-H generator system was used as the power source.Results The hyperbaric oxygen chamber ambulance could stably control the chamber pressure when the therapeutic pressure was set as 1.3,1.6 and 1.8 ATA(1 ATA=0.1 MPa),the volume fraction of oxygen in the chamber could be limited within the required range under the low oxygen volume fraction mode and high oxygen volume fraction mode,and the emergency decompression time could be restrained within 60 s.Conclusion The hyperbaric oxygen chamber ambulance behaves well in maneuverability,and can be used for on-site hyperbaric oxygen treatment and transport of casualties.[Chinese Medical Equipment Journal,2024,45(10):25-30]
